Galactic Civilizations IV is a deep and immersive turn-based 4X grand strategy game, where you lead your own interstellar empire and expand across the stars. Set in a universe that has just discovered faster-than-light travel, the game challenges you to build a thriving civilization, explore new worlds, research powerful technologies, meet alien species, and fight to thrive in a competitive galaxy.
Whether you enjoy peaceful expansion or galactic domination, Galactic Civilizations IV gives you complete strategic freedom to shape the future of your empire.
Build the Empire of Your Dreams
As the leader of a new space-faring civilization, every decision matters. You will:
-
Explore distant star systems
-
Establish colonies and Core Worlds
-
Build advanced starships
-
Develop breakthrough technologies
-
Negotiate or go to war with alien factions
The galaxy isn’t always friendly. Other civilizations have their own goals, ideologies, and powerful AI-driven strategies. Your ability to adapt determines your path to survival.
4X Strategy Meets Deep Narrative
Galactic Civilizations IV combines classic 4X gameplay (Explore, Expand, Exploit, Exterminate) with grand strategy depth.
A built-in narrative system and advanced AI create a universe that feels alive, where every faction follows unique agendas and reacts intelligently to your decisions.
Each playthrough delivers new stories, rivalries, alliances, and outcomes based on your playstyle.
Create Your Own Civilization
One of the standout features is AlienGPT, allowing you to design a fully customizable civilization from scratch. Simply describe your society’s traits, personality, and goals — the AI generates:
-
Original lore
-
Diplomatic behavior
-
Starship designs
-
Unique ambassadors
No two empires feel the same, making every campaign personal and replayable.
Play Tall or Play Wide
Galactic Civilizations IV introduces a flexible economic and resource management system:
-
Tall play: Focus on a few highly developed Core Worlds supported by multiple Colonies
-
Wide play: Expand aggressively, improve many planets, and rule through numbers
Both strategies are viable and rewarding, giving players meaningful choices for empire growth.
Design Your Own Starship Fleets
With the Ship Designer, you can create powerful interstellar fleets that reflect your tactical style. Choose hull types, weapons, propulsion systems, and defense modules to build warships suited for your chosen strategy — whether you value speed, firepower, or endurance.
Deep Strategy Made Accessible
Game sessions can be short or epic in scale. You can enjoy quick one-hour matches or commit to long-term campaigns that evolve over time. Diplomacy, culture, ethics, and military strength all play significant roles in shaping the destiny of your empire.
